I created a Cluster Server 2012 two node Cluster. We then presented some SAN space to each server on the same subnet. From Failover Cluster Manager I added a Disk from Node 1 and a Disk from Node 2. Now Cluster Disk 1 shows as Offline and Cluster Disk 2 shows as Failed. I ran the Storage tests from the Validate Configurations task, it shows for both disks:
Physical disk 41642f8c is visible from only one node and will not be tested.
What needs to be different?
